【明報專訊】ACCORDING TO a number of university teachers in mainland China, the authorities have recently issued instructions to all institutions of higher learning, telling teachers not to discuss with students seven topics, namely universal values, freedom of the press, a civic society, civic rights, historical mistakes made by the Communist Party, elite cronyism, and judicial independence. While this gag order has not been officially confirmed, it has become a sensitive search item blocked on Sina Weibo. This is really disturbing.
